' i This invention relates to paper makingmachinery having particular reference to the filling of'theshells of what are known as Jordan enginesiESuch shells have a lining'which may :55138 all, metal but is generally'madeup of'knives and separatingmembers known as woods, both angularly" bent and so; arranged that' the knives project inward beyond the wooden separators. I As these knives .and separators wear down, they must from time to timebe replaced. and this canbe done individually by buildingthem up in the paper mill, .or preferably. they,canbe assembled at the factory and'shipped. as a lining.

' As wood is generally used for separatora when in transit any length of time, the woodldriesand shrinks, and as the lining must" fit very ac-' V curately to the shell, 'it'has been found that one or more wedges which are also separators, are" very convenient to expandthe lining and fit theshella" A preconstructed lining might collapse unless the knives and separators were strung. on wires,

held in a jacket and spot welded, or held in a jacket and provided with ribs and grooves like that shown in my application, pending herewith,

In the drawing, Alrepresents the permanent one of the holding a holding ring of shell of; a Jordan engine and B represents onev assembled lining or filling therefor. There are' 'usuallylthree of such fillings of varying di'- ameter'so that the smallest can be positioned Y in the permanent shell, then the next and-them -thelarge'st.'k "The knives C,fC,"asshown, are of thensualangularv construction, that is they .are bent across-the middle portion in a well known man 11 D, represents the members which serve to separate the knives and include the wooden members such as the wedge 12, the especially shaped members 10 andfll, and the members 13, which" latter comprises" 'mostbf the. separators. These'have anangular bend "or are cut angularly to fit between the knives C, 'C, while the members 10 and 11 are cf special shape so that awedge like 12 can be slipped in betwe'en them. Anotherseparator is lewhi'ch' usually is made of metal an'dhas recesses through which 7 filling in the permanent shell? V v I F represents a' sheet metal ring of a size screws'orbolts can pass toihold the assembled slightly smaller than the large end; and Grep- V resents asimilariring slightly smaller than the at the large end, nails 30 are driven preferably into the end of each wooden separator such as 11, 12 and 13, or every alternate separator, or at such intervals as may be desired.

Opposite the large end of one or more of the wedges such as 12, the metal may be cut away so that as shown in Fig. 5 the part 32 can be bent out allowing the wedge to be partially driven out from the small end so that it pro jects at the large end.

I prefer to use in connection with the end holding rings, nails such as 20 which have heads 21 and 22 which are respectively on each side of a ring such as G. When these are driven in forming holes 26, and it is desired to remove the ring, all the nails will come off with it, avoiding any danger of leaving any nails in the engine.

I prefer to use knives such as those shown in end view at C in Fig. 4, having on each side a projecting longitudinal rib 15, 15, and to associate with them, Wooden separators such as D having corresponding longitudinal grooves 25. When such knives and separators are assembled they hold each other in place and prevent collapsing. I

As I assemble my linings in a suitable form, the knives and separators cannot move outward until the form is removed, and before it is removed I attach the rings such as F and G, and these permit the assembled lining to be removed and shipped with no danger either of collapsing or spreading.

When my assembled linings are to be used in a permanent shell such asA shown in Fig. 5, the smallest section is positioned in toward the small end of shell A at which there is usually an inwardly extending annular flange '5, and when far enough in so thatit practically touches all the way around, the ring G at the small end is ripped off, twisted and pulled throughthe small end of the shell A as shown.

The sections such as32 of the large ring may then be bent out or the whole ring may be removed so that one or more of the fitting wedges 12 can be driven back from the small end thus allowing the whole assembled filling to be pushed in close up against flange 5. Its parts are then evened up and the wedge or wedges 12 driven completely in so as to keep it tightly in place. 'As shown in Fig. 6, instead of a single continuous sheet metal ring at each end I can use sections such as 40, 41 and 42 which overlap in such a manner that certain nails such as 44 can be driven through two sections while others such as 43 are driven through one only.

Instead of metal rings I can, as shown in Fig. 7, assemble the knives such as 50 shown in Fig. 7 and separators 51 in suitable form, and then I can drive the long staples 52 in staggered relation so as to pass'over the ends of the knives and into adjoining woods as shown.

In this view, the knives and separators have neither ribs nor grooves. I

.In Fig. 9 the knives C and separators D are held together by means of staples 53, 53, of which preferably there are two driven diagonally into the separators on each side of each knife so as to straddle the knife. I I In Figs. 10 and 11 I show another type of what might be called multiple staples 63, each of which may have more than two prongs 64 which aredriven into the separators 61, 61', straddling the knives 60. I show in Fig. 10 splines 62, 62, entering suitable grooves in a knife and ad- 'metal leaving corresponding holes 71.

While I prefer to use my end holding device merely while the assembled filling is being shipped from the factory to the paper mill and while it is being put in position inside the per manent shell, I may leave them in place, if necessary cutting such rings as F or G to allow any necessary expansion.

In the construction shown in Figs. 7 and 9 the staples such as 52 or 53 can be sunk in suitable recesses so that most of them can be left in place after the lining has been fitted to the permanent shell.

In such case also it is apparent, to permit a wedge separator such as 56 shown in Fig. 7, to be driven back, the three staples 52,52, 52, which hold it can be pulled out.

It is also obvious that a combination of the various means disclosed can be used if desired as shown in Fig. 14 where I show knives 80, and between them, ordinary separators 81 or wedge shaped separators 82 in some places being held together by staples 52v and in other cases by plates such as 47, through holes 7 in which nails 48 are driven into the separators 81 or 82.

It may be convenient in some cases to use the, wedge such as 12 which is in position while the lining is being transported merely as a temporary matter and after the lining section is almost in position to drive this temporary wedge out from the large endand put in place thereof a permanent wedgewhich may be slightly larger or smaller. The cuts 232, 232, which make the bendable section .32 should be of such depth and such distance apart that the large end of the wedge can pass through them leaving a connecting portion ,132 which holds the assembly together when the wedge is driven wholly or partly out.

This connecting section 132 can be allowed to buckle slightly if it is desirable that the large ring F should contract, but if it becomes necese sary to expand the lining beyond the size of the large ring F, that ring must be entirely removed. I

I prefer to use a type of knives and separating members having ribs and grooves or other equiv:

alent construction such as shown in Fig. 4 as this keeps them from displacement towards the axis of the shell.

I claim: I

1. The combination, in a bodily transportable lining for'Jordan engine shells of a plurality of knives and members which serve toseparate them, each knife and member being of such form that it cannot move inward without moving with it both adjoining members or knives, or the adjoining member or knife; with a flat ring at each end each ring having projecting nails which are driven into the ends of the separating members.

' 2. The combination in a bodily transportable lining for Jordan engine shells of a plurality of form that it cannot move inward without moving with it both adjoining members or knives, or the I adjoining member or knife; with means at their ends to hold the knives and members in assembled relation. I r p 3. The combinationin a bodily transportable lining for Jordan engine shells of a plurality'of knives; with a plurality of separating members positioned between the knives, one of said separating members being a wedge; and means at their ends to hold them together, such means being so formed as to permit such wedge to be removed from its large end.

4. The combination in a bodily transportable lining for Jordan engine shells of a plurality of knife members and members which serve to' separate them; with a flat ring in position at each end of the assembly; and a plurality of members associated with each ring which connects it with the ends of some of the assembled members.

5. The combination in a bodily transportable lining for Jordan engine shells in the form of a hollow truncated cone, of a plurality of knife members and separating members which serve to separate them; with a ring at each end to which ring are attached penetrating members introduced into the ends of enough of the separating members to hold the assembly together.

6. The combination in a bodily transportable lining for Jordan engine shells in the form of a hollow truncated cone, of a plurality of knife members and separating members which serve of-staples sodriven into the ends of some of the separating members as to hold the assembly by locking the members together.

8. The combination in a bodily transportable lining for Jordan engine shells in the form of a hollow truncated cone, of a plurality of knife members and separating members which serve to separate the knife members; with a flat ring at each end, each ring having projecting nails which are driven into the ends of some of the separating members to hold the assembly together.
